Introduction Thank you for purchasing this Zero Gravity Ultima 4 Trampoline. This trampoline was manufactured using

the highest quality materials and skills gained over decades of trampoline production. If proper care and

maintenance is provided then we’re sure that it will provide years of fun and exercise for the whole family.

We cannot state how important it is for the owners and users of this trampoline to have a thorough

understanding of the rules for proper use. Children must be supervised at all times by a knowledgeable and

mature adult while using the trampoline. When there is to be no adult supervision available then take precautions

to prevent access to the trampoline by children or unauthorized users who do not have your consent to use the

trampoline.

Carefully read and understand all of the instructions and warnings in this guide before assembling and

using this product. It is the responsibility of the owner of this trampoline to ensure that all users of this product are

fully informed on the proper use and the inherent risks of jumping on a trampoline, failure to do so can result in

serious injury or death. In particular, under no circumstances should you attempt or allow flips, somersaults or

any similar behaviour. Landing on the head or neck can cause serious injury, paralysis, or death. Never allow

more than one person on the trampoline at any time as this can dramatically increase the risk of injury.

To reduce the risks associated with a user falling off the trampoline, the enclosure netting must be

properly installed and used at all times. The trampoline enclosure entrance must be closed during use to prevent

the user from falling off the trampoline. Although your trampoline enclosure netting is manufactured with UV

resistant material, exposure to the elements will weaken the netting over time. Therefore the netting and mattress

must be inspected prior to every use and maintained regularly as detailed in this guide.

Location of the trampoline is extremely important in order to reduce the risk of injury. The intended site for

the trampoline must be completely flat and level. If the ground is not completely flat then it can cause movement

in the frame and put stress on the joint sections which could cause damage to the trampoline and make it unsafe

for use with the risk of causing serious injury. The trampoline must only be located on a soft surface such as

grass or cushioned play area. Siting the trampoline on a hard or slippery surface such as paving, concrete,

decking or astroturf will cause damage to the trampoline and put users at risk. The trampoline must be clear from

overhead hazards such as power cables and tree limbs with at least 8 metres overhead clearance from ground

level. Site the trampoline at least 2.5 metres away from any structure or obstacle.

The trampoline must never be used in windy conditions as this can cause unexpected movement of the

product. Wind can cause the trampoline to be lifted from the ground and become airborne presenting a danger to

individuals and to property. We always recommend that you anchor or secure the trampoline to prevent it from

moving as a result of the wind. We highly recommend consulting a local licensed tradesman to best determine

how to implement an anchor system for your specific conditions. Even with anchors in place a trampoline can be

lifted by strong winds. If high winds are forecast the trampoline should be disassembled and stored away safely

until the weather conditions improve. Damage from the wind or other severe weather is not covered by the

manufacturer’s warranty.

Only genuine Zero Gravity replacement parts sold through an authorized dealer should be used.

Replacement parts produced by any other manufacturer may not have met the design and extensive safety

testing standards used in the production of this Zero Gravity trampoline. As a result of this Zero Gravity

Trampolines will not guarantee the performance and safety of the product when non-genuine replacement parts

are used. The use of non-genuine Zero Gravity replacement parts may affect any warranty claim on the product,

as allowed by the law in your jurisdiction.

Before you start to assemble

Check the contents of your package against the parts list in this guide. If any parts are missing please

contact your supplier or Zero Gravity Trampolines customer service for assistance.

If any parts are missing or damaged then do not erect or use the trampoline until replacement parts

have been received.

When choosing the location for your trampoline please ensure that the area is completely flat and level.

The trampoline should be clear from obstructions overhead; we recommend 8 metres clearance from

ground level. Ensure that there is a minimum of 2 metres clearance from any structure or obstruction

around the edge of the trampoline. There should be no obstructions underneath the trampoline and it is

preferable to select a well-lit area.

Two adults are required to erect the trampoline.

We recommend wearing heavy duty work gloves and eye protection when assembling the trampoline.

The trampoline has passed extensive safety testing. Do not modify the design of the product in any way

nor use non-original Zero Gravity parts.

The packaging does contain some small parts which are a choking hazard for small children. It is

therefore recommended that children under the age of 3 years should be kept away when the

trampoline is being assembled.

Ensure that you keep this instruction manual for future reference.

Before using the trampoline Use of this trampoline requires constant adult supervision. Use the trampoline only with mature and

knowledgeable ADULT supervision.

Ensure that the trampoline enclosure has been assembled correctly, as per the instructions in this

manual and that the zipper and buckles located at the entrance are fully closed before use.

Trampolines over 20 in. (51 cm) tall are not recommended for use by children under 6 years of age.

There must be no more than one person at a time on the trampoline.

Maximum weight of the user must NOT exceed 220lbs/100kg for this product.

This product is for household and family domestic use only – It is not for use in schools, playgrounds,

rental or commercial use.

It is of particular importance to follow the maintenance instructions at the beginning of every season.

Neglecting regular maintenance can lead to a risk for users.

Important Safety Instructions

The enclosure forms part of the structural integrity of the trampoline. The trampoline must not be used

without the enclosure erected.

Only one user at any one time! Multiple users can cause loss of control, collision or falls on the

trampoline. This could result in serious injury to legs, arms, back, neck or head.

Do not use the trampoline when under the influence of alcohol, drugs or medication, as this may impair

the jumper’s judgement.

Always consult your physician before performing any kind of physical activity.

Do not use the trampoline if you have high blood pressure.

Do not use the trampoline if you have a medical history of neck or back injuries or mental or physical

conditions that could cause injury.

Do not use if the user has any broken bones (casts) or has recently been in the hospital for extensive

treatments (operations, severe wounds, stitches, back injury or concussion).

If pregnant, do not use without the consent of your physician.

Do not use the trampoline if the user or the trampoline surface is wet. These conditions can cause the

user to lose control and fall resulting in serious injury.

The product must not be used in windy conditions as wind can cause unexpected movement of the

product. Wind can cause the trampoline to be lifted off the ground and become airborne. This can

present a danger to individuals and to property. Winds can be especially strong in open areas, areas

between homes that create wind tunnels and anywhere else where local weather conditions can create

high winds. We recommend that you anchor the trampoline or otherwise secure the trampoline to

prevent it from moving as a result of the wind. One possible way to anchor the trampoline is to secure

the trampoline to a concrete footing under each leg. We recommend consulting a local licensed

contractor to best determine how the anchor system should be constructed for your specific conditions.

When anchoring the trampoline, straps must always be connected to the top ring of the trampoline, not

the feet, as legs could be separated from the main frame in strong winds. Even with anchors a

trampoline can be lifted, just like anything else, by strong winds. If the winds are anticipated to be very

strong, the trampoline should be disassembled and stored away safely until the weather conditions

improve. Damage from the wind or other severe weather is not covered by the manufacturer’s warranty.

Because the manufacturer warranty does not cover wind or weather related damage and damage can

be caused to your property or the property of others by a windblown trampoline, it is strongly advised

that you provide site specific anchoring through a licensed local contractor.

Only use trampoline with mature, knowledgeable adult supervision.

Do not attempt or allow somersaults. Landing on the head or neck can cause serious injury, paralysis, or

death, even when landing in the middle of the mat.

Carefully read these warnings before using this product. Failure to follow these warnings can result in serious injury or death.

6

Do not allow more than one person on the trampoline. Use by more than one person at the same time

increases the chance of injury.

Proper Play Conditions:



Always use the product in a well-lit area. Do not use without lighting during dawn, dusk or in complete

darkness.

The trampoline must be placed on a surface that is COMPLETELY FLAT AND LEVEL. If the ground is

uneven, this could cause movement in the frame, stress on the joined sections and could damage the

trampoline and/or can cause serious injury.

DO NOT install or position this trampoline on a hard surface such as concrete, tarmac, decking,

astroturf or paving. Suitable surfaces are grass, sand or a play area covered with an appropriate depth

of play bark material.

ALWAYS ensure the trampoline is on level ground with a minimum of 8.2ft (2.5 metres) clear space

from any structure or obstruction such as a fence, garage, house, overhanging branches, laundry lines

or electrical wires.

Adequate overhead clearance is essential. A minimum of 26.25 ft (8 metres) from ground level is

recommended. Provide clearance for wires, tree limbs, and other possible hazards.

Do not use the trampoline indoors, as this product is intended for outdoor home use only.

Appropriate Use Conditions:

Children must always be supervised while they are playing on the trampoline and must be instructed

not to use the trampoline in an inappropriate or hazardous manner. Take precautions to prevent access

to the trampoline by children when there is no adult supervision.

Restrict access to the trampoline by any unauthorized users.

Trampolines are rebounding devices which propel the user to unaccustomed heights and into a variety

of body movements. Rebounding off of the trampoline, striking the frame or springs, or improperly

landing on the trampoline mat may cause serious injury.

Always start and maintain your jump at the centre of the trampoline mat in order to reduce the risk of

landing on the frame or springs or falling off the trampoline. When you land more than 1ft away from the

edge of the Zero Gravity logo in the centre of the mat stop your jump immediately. Restart your jump at

the centre of the mat.

Avoid bouncing too high. Stay low until you can control your bounce and land consistently in the middle

of the trampoline mat.

Carefully read these warnings before using this product. Failure to follow these safety instructions can result in serious injury or death.

7

Ensure the trampoline frame and springs are fully covered by the frame pad to avoid any direct contact

with metal parts.

Do not stand or jump on the springs while using the trampoline. The springs are not designed to

support such stress and weight. This can result in serious injuries and/or product damage. If you see

any signs of stretched or damaged springs, do not use the trampoline until replacement springs are

properly installed. Please contact our customer service representatives to order original Zero Gravity

replacement parts.

The trampoline is several feet off the ground. Jumping off the trampoline to the ground or any other

surface may result in injury. Smaller children may need assistance getting up onto or down from the

trampoline. Mounting and dismounting properly should be followed as a strict rule. Users should climb

onto the trampoline by placing their hands on the frame and stepping or rolling up onto the frame,

across the springs and onto the mat. Do not step directly on the frame pad or grasp the frame pad

when mounting or dismounting the trampoline. To dismount, jumpers should walk to the side of the mat,

bend over and place their hands on the frame, then step from the mat to the ground. Users should

always place their hands on the frame while mounting or dismounting.

Do NOT use the trampoline as a springboard to jump onto other objects.

Remove all objects not designed for use with the trampoline from the trampoline before use. Do not let

children take toys or other items onto the trampoline.

Do not eat while jumping.

The trampoline should not be buried or sunken into the ground.

During winter period, the snow load and the very low temperature can damage the trampoline. It is

recommended to remove the snow and store the mat and the enclosure indoors.

Do not jump or step onto the frame pad as it was not designed to support the weight of a person.

Do not use the trampoline while holding or wearing any type of sharp or pointed objects such as

jewellery, watches, rings, eyewear and necklaces before using this product. This will prevent the

jewellery from tearing the mat or getting caught in the enclosure netting.

Do not wear loose fitting clothing that may catch or snag during play.

Never wear footwear (e.g. shoes) when using the trampoline.

Always tie back long hair so that it does not block user’s vision or get caught in the enclosure netting.

FRAME PADS – Frame pads are there to protect user from any fall or landing on the springs and frame.

On no account should people be permitted to sit or stand on them when the trampoline is in use. You

should also make sure that smaller users do not use the inside edges of the pads as a “handle” when

getting up on to the trampoline.

Never use the trampoline without the frame pad being securely attached. Properly tie down the frame

pad before each use. Improper assembly of the frame pad may lead to injury.

Always check to ensure there are no obstructions or objects under the trampoline that could cause

injury or obstruct movement of jump mat. Also check that there are no pets or other people underneath

the trampoline.

Do not jump on the trampoline with a snowboard, skateboard, roller blades, bicycle or any other

equipment. DO NOT hold any foreign objects not authorized by the manufacturer in your hand and DO

NOT place any objects on the trampoline while anyone is jumping on it. Please be aware of your

8

surroundings to ensure there are no objects that could cause harm when you are playing on the

trampoline.

The frame of your trampoline is made of steel and it will conduct electricity. No electrical equipment

(lights, heaters, extension cords, household appliances, etc.) should be permitted in, on or around the

trampoline under any circumstances to avoid the risk of electrocution.

Always jump in the middle of the mat.

Enclosure Netting and Mat – Appropriate Use Conditions

Children MUST NEVER be left unattended inside the enclosure at any time.

The enclosure is ONLY intended to be used to reduce the risk of injury from falling off the trampoline.

Do not intentionally kick, bounce against, climb on, hang from, jump over or crawl under the netting.

Enter and exit the enclosure only through the zipper door. Do not go through the gap between the

netting and the mat. Trying to exit this way poses a risk of strangulation, especially for young children.

The enclosure netting and mat must be inspected prior to each use. If there are any signs of weakness,

you must stop using the trampoline immediately, properly store the trampoline and restrict access by

users until a new Zero Gravity authorized replacement netting or pad is installed. Please refer to the

Trampoline Net & Pad – Maintenance Requirements section contained in this manual for further details.

32

Lowering the Trampoline Enclosure

STEP 1

Note:

Enclosure poles can be stiff to

remove if not taken down

frequently. If tight, spray a small

amount of lubricant such as

WD40 or silicon spray around the

pole and shake the pole so

lubricant gets in to the joint.

33

STEP 2 – STOW ENCLOSURE POLES

Note:

Lift each of the poles up

from the floor and over on

to the trampoline

mattress.

34

Moving the Trampoline

To move the trampoline we strongly recommend that the trampoline be disassembled and then

reassembled in the new location. If however you only require the trampoline to be moved a short distance

two people lifting is required. Do not pick up the frame more than 2 inches from the ground, raising it too

high can cause the frame to warp. If the frame does warp then put the trampoline down and press down on

the part that is warped. The tension in the springs will flatten the frame.

On no account should the trampoline be dragged across the ground as this can damage the structure of the

trampoline. The trampoline must be kept steady and horizontal during the move. Failure to follow these

instructions can result in a leg joint being damaged or coming loose which, when the trampoline is in use,

may cause serious injury or death.

35

Care and Maintenance

Enclosure netting, mattress and padding will be prone to wear. Gradual deterioration of the material will

occur; the speed of which will depend on a number of factors including the level of exposure to UV rays,

airborne pollution and outdoor weather conditions such as rain and wind.

The net, mattress and padding needs to be properly maintained and checked by following the Maintenance

Schedule set out in these instructions. When the material shows any signs of weakness, you must stop

using the trampoline immediately, properly store the trampoline and restrict access by users until

replacement of the worn component is properly installed.

Official Zero Gravity replacement parts can be purchased from our website:

www.zerogravitytrampolines.com

Maintenance Requirement for Trampoline Frame

Check that legs are in a vertical position, all nuts and bolts are secured, and that all frame securing pegs

are in place.

Maintenance Requirement for Trampoline Mattress

Visually check for any material deterioration, tears or burn holes (falling embers from a fire will burn through

the mattress) in the mattress. Check the spring connecting V-Rings for any damage to stitching. The

mattress must be immediately replaced if any faults are found.

Maintenance Requirement for Trampoline Pad

Walk around the whole perimeter of the trampoline to visually check for any material deterioration, tears,

looseness, loss of elasticity in securing ties or other damage in the pad. The padding must be immediately

replaced if any faults are found.

Maintenance Requirement for Enclosure Net

The netting is exposed to outdoor elements including sunlight, wind and rain. The net surrounding the

trampoline must be checked prior to each use. This includes, but is not limited to inspecting the net for

cracks, excess wear, brittleness, and stretching. In addition you will need to inspect all connections and the

entire enclosure for overall integrity. The net must be immediately replaced if it shows any signs of wear,

damage, stretching, cracking, looseness, brittleness or other losses in integrity. The following Maintenance

Schedule must be followed:

1 to 3 Months 3 to 6 Months 6 to 12 Months

Inspect the enclosure (net, net hanger, and straps) prior to every use.

Thorough inspection for UV damage and prior to every use for net, net hanger and straps.

Thorough inspection before every use on net, net hanger, straps, zippers, ties and strings. Replace after 12 months or earlier if necessary.

Failure to follow these instructions to ensure proper operational condition of your trampoline may lead to serious injury or death.

36

IT IS RECOMMENDED THAT THE NET BE REPLACED ON A YEARLY BASIS UNDER NORMAL USE, EVEN

IF IT DOES NOT SHOW ANY VISIBLE SIGNS OF DAMAGE.

How to Inspect the Trampoline Net for Structural Integrity

Always check the entire enclosure netting for signs of UV damage, deterioration, brittleness, cracking, and

tearing every time before using the trampoline and enclosure.

Step 1 - Inspect the enclosure netting before EACH use for wear or tear by pinching and pulling a section of

the netting between fingers and pulling downward. Please see diagram below.

If it produces any tear, cracking or ripping sound, then the net is unsafe and MUST be taken down

immediately. STOP USING THE TRAMPOLINE ENCLOSURE IF YOU FIND ANY SIGNS OF WEAR OR

TEARING ON THE NETTING.

It is recommended that you replace the trampoline enclosure net and pad every 12 months. Replace the

enclosure net and pad earlier if there are any signs of wear, tear, brittleness, cracking, stretching or any

other signs of weakness. New enclosure netting and pads can be purchased through Zero Gravity

Trampolines customer service or on our website www.ZeroGravityTrampolines.com

Instructions for use

Responsibilities of the user

The key here is to stay in control of your jumps. DO NOT move onto more complicated, more difficult

manoeuvres until you have mastered the basic, fundamental bounce. Read, understand, and practice all

precautions and warnings prior to using the trampoline. A controlled jump is when you land and take off from

the same location. For additional tips and instructions, contact a certified trampoline instructor.

Supervisor’s or owner’s role in preventing injuries

It is the responsibility of the supervisor(s) of the trampoline users to provide knowledgeable and mature

supervision. They need to know and enforce all the rules and warnings set forth in this manual in order to

minimize the likelihood of accidents and injuries and to inform users of these rules. During the periods of

time when supervision is unavailable or inadequate, the trampoline should be disassembled and stored in a

secure place to prevent unauthorized use. The supervisor is also responsible to ensure that the safety

placard is placed on the trampoline and that the jumpers are informed of these warnings and instructions.

All jumpers need to be supervised, regardless of skill level or age.

DO NOT attempt or allow somersaults. Landing on the head or neck can cause serious injury,

paralysis or death, even when landing in the middle of the mat.

Do not allow more than one person on the trampoline. Use by more than one person at the same time

can result in serious injuries.

Trampolines over 20 inches (51 cm) tall should not be used by children under six (6) years of age.

Wear clothing free of drawstrings, hooks, loops or anything that could get caught while using the

trampoline/enclosure and result in entanglement or strangulation, or both.

Climb on and off the trampoline. It is a dangerous practice to jump from the trampoline to the floor or

ground when dismounting, or to jump onto the trampoline when mounting. Do not use the trampoline

as a springboard to other objects.

Keep enclosure tightly fastened to the trampoline in accordance with the manufacturer’s instructions.

Failure to properly assemble and maintain a tight, secure trampoline/enclosure boundary may result in

serious injury, strangulation or death.

Completely close the opening of the enclosure before jumping. Close the opening of the enclosure

after using the trampoline.

Do not use the trampoline while under the influence of alcohol or drugs.

Read and understand the instructions for use in this manual prior to using this product. Failure to do so can result in serious injury or death.

38

Do not attempt to jump over the enclosure netting.

Do not intentionally rebound off the enclosure netting.

Read all instructions before using the trampoline. Warnings and instructions for the care, maintenance

and use of this trampoline are included to promote proper and enjoyable use of this equipment.

Inspect the trampoline before each use. Make sure the frame padding, enclosure and the enclosure

support (frame) padding is correctly and securely positioned. Replace any worn, defective or missing

parts before using.

Use trampoline only with mature, knowledgeable adult supervision.

Lateral clearance is essential. Place the trampoline away from walls, structures, fences and other play

areas.

Maintain a clear space of 2.5 metres on all sides of the trampoline. For safe use of the trampoline,

please be aware of the following when selecting a place for your trampoline.

Place the trampoline on a level surface before use, illumination may be required for shady areas.

Secure the trampoline against unauthorised and unsupervised use.

Remove any obstructions from beneath the trampoline.

The owner and supervisors of the trampoline are responsible to make all users aware of practices

specified in the use instructions.

Not suitable for children under 3 years. Small parts are a choking hazard and long cords are a

strangulation hazard.

Only one user at a time. Collision hazard.

Adult supervision required.

No somersaults.

All nuts and bolts must be checked for tightness and if necessary must be retightened.

If self-locking nuts are used, it should be noted that these are only suitable for one assembly and must

therefore be replaced.

Check all coverings for burrs and sharp edges and replace affected parts if necessary.

Check for loose cords and gaps. Users may become entangled in or strangled by loose cords or in

gaps between trampoline and enclosure.

Use trampoline only when the surface of the mat is dry. Wind or air movement should be calm to

gentle. The trampoline must not be used in gusty or severe winds.

Read and understand the use instructions in this manual prior to using this product. Failure to do so can result in serious injury or death.

39

Keep objects away which could interfere with the jumper. Maintain a clear area under, above, and

around the trampoline.

Do not attempt to crawl under the netting.

Do not hang from, kick, cut or climb on the netting.

Do not attach anything to the netting that is not a manufacturer-approved accessory or part of the

enclosure system.

Enter and exit the enclosure only at the enclosure door.

Learn fundamental bounces and body positions thoroughly before trying more advanced skills. A

variety of trampoline activities can be carried out by performing the basic fundamentals in various

series and combinations, performing one fundamental after another, with or without feet bounces

between them.

Stop bounce by flexing knees as feet come into contact with the trampoline mat. Learn this skill before

attempting others.

Avoid bouncing too high. Stay low until bounce control and repeated landing in the centre of the

trampoline can be accomplished. While keeping the head erect, focus eyes on the trampoline toward

the perimeter, this will help control the bounce. Control is more important than height.

Avoid bouncing when tired. Keep turns short.

Limit the time of continuous usage. Make regular stops. Do not jump when tired.

Properly secure the trampoline when not in use. Protect it against unauthorized use. If a trampoline

ladder is used, the supervisor should remove it from the trampoline when leaving the area to prevent

unsupervised access by children under six (6) years of age.

For information concerning skill training, contact a certified trampoline instructor.

For additional information concerning the trampoline equipment, contact the manufacturer.

The trampoline shall be assembled by adults in accordance with the assembly instructions and

thereafter checked before the first use.

Empty pockets and hands before jumping.

Do not exit by a jump.

Fundamental trampolining skills

The following lessons are suggested in order to learn basic steps and bounces before moving onto more difficult,

complicated bounces. Before actually getting on and using the trampoline, you should read and understand all

safety instructions. A complete discussion and demonstration of body mechanics and trampoline guidelines

should occur between the supervisor and student as well.

Lesson 1

A. Mounting and Dismounting-Demonstration of proper techniques

B. The Basic Bounce-Demonstration and practice

C. Braking (Check the Bounce-Demonstration) and practice. Learn to brake on command

D. Hands and knees-Demonstration and practice. Stress should be on four-point landing and alignment

Lesson 2

A. Review and practice of techniques learned in Lesson 1

B. Knees Bounce-Demonstration and practice. Learn the basic down to knee and back up before trying half twist

to left and right

C. Seat Bounce-Demonstration and practice. Learn basic seat bounce then add a knee bounce, hands and

knees; repeat

Lesson 3

A. Review and practice skills and techniques learned in previous lessons

B. Front Drop-To avoid mat burns and teach the front bounce position, all students should be requested to

assume the prone position (face down on the ground) while the instructor checks for faulty positions that could

cause injury

C. Start with a hands and knees bounce and then extend body into prone position, and on the mat and

return to feet

D. Practice Routine-Hands and knees Bounce, Front Bounce, back to feet, seat bounce, back to feet, seat

bounce, back to feet

After completing this lesson, the student now has a basic foundation of trampoline bounces. Jumpers should be

encouraged to try and develop their own routines with the emphasis on control and form.

A certified trampoline instructor should be contacted to further develop your trampoline skills.
